Application filed August 18. 1913. Serial No. 785.305.

T 0 all 40/ 10112. it may emzcc n Be it known that .l. .llnoonrn Glaser, a citizen of the United Slates. and a resident of Toledo. in the county of Lucas and State of Ohio. have inventml a certain new and useful Air-(handing Device; and l (lo-hereby declare the following: to be a full. clean, and exact description of the. invention. such as will enahlcotlurrs skilled in the art to which it appertains to make and use the. same. reference being ha d to the accompanying drawings. and to the characters oi reference marked thereon. which term a part of this specification.

My invention relatesv to :uitomatic pncu: matic couplers.

It is )articularly applicable to railway trains wherein the brakes are. operated pueumatically. It. however. maybe used to pro vide a means for connecting together pipes which form a connection between an air supply tank or a pump and an operative mechanism, such as a brake. It maybe used for connecting pneumatically controlled devices with a. central controlling device or with controlling devices. It also may be used for connecting together pipes which convey gases or vapors between two bodies movable with respect to each other.

The invention may be contained in a great many forms of devices as well as used for many purposes. I shall describe hereinafter and show in the drawings one of the many constructions containing the invention. The particular construction shown, I have selected as an example to illustrate how such a structure may be constructed and ma nipulated and to show that it. is operative.

Referring to the drawings, Figure 1 illustrates one view of the structure selected. Fig. 2 illustrates a side view of the construction showing parts in section. Fig. 3, illustrates an end View, one part being removed. Fig. 4 is a vertical sectional view of the construction. Fig. 5 is :1V View of a connecting pipe, a detail shown in other of the figures. and Fig. 6 illustrates a l'accview of a contact sealing plate.

1 is a frame which comprises the base 2, the upright supporting plate 3 and the brackets 4;. A flanged coupler or c nnector is secured to the upright 23 and connects the device with the air suppl} or other system having vacuum capaeitv or gas or vapor samply. A. shell or-slm'eve. '7 provided with a l ail-and-soelaet joint S t) which connnnnit-ates with the interiors of the flanged con pier 5 and the shell. The shell or sleeve 7 is provided with a bearing 10, which is located on an extending boss or arm 11. This permits the sleeve 7 to rotate about a horizontal axis at right angles to its own axis. The bearing 10 is supported by a rack 15 con'iprising the horizontal plates 16 and. the vertical plate 18. The plates 16 are secured to the outer ends of the vertical plate 18. The rack 15 is pivoted to move about a vertical axis passing through the ball-audsoeket joint 8----9 by means of the bearings 19 fm'med oi bosses in. the upper and lower ends of the vertical supporting plate 3. The plates to are secured in position by means of the nuts 90 and washers 21. The connecting plate 18 bears against theshoulder 12 on the arm or lug t1 and is held in position by means of the nuts 22 located on screws extending tron; the horizontal plates 16 through the ends of the plate 18. A spring 24 located between the shoulder .lfiand the plate 18 keeps the ball 8 seated in its socket 9. This permits the shell to rotate about a vertical axis and prevent leakage at the point o't eormection.

'lhe shell is held normally horizontally by the springs 30. which are located between one end of the shell 7 and. right angular exteusionsfll forming parts of the horizontal plates 16 located above. and below the shell 7. Bosses or spring seats and 33 are located upon the extensions 31 and on opposite sides of the shell 7. These retain the springs 30 in position.

The shell 7 is normally held. centrallyand its axis normally maintained parallel with the face of the vertical plate 3 by means of two springs 35. which are located on the 0ppositc sides of two extending lugs or pins 36 secured to or forming a part of the con- I necting plate 18 located on the rack 15. The pins 36 yoke over or spread a rod 3?, which -1s supported by means of the brackets 4 and c'ompressed,

vided with shoulders or form seats for the springs 35. The collars" is secured in position by means ofthenuts,

or collars 39, which also 38, and shoulders I 35 in pos1- form seats to hold the springs tionQ Collars 40 are locatedbetwen the s rin 35 and the ins 36. They are prop gs p bosses 41 which also 40 are. freely movable along the rod 37 As the rack ismovedon the bearings 19 one or'the other of the springs 35 is more or less which tends to cause the return of the shell i cor-tube 50 is located centrally in the's' e l or sleeve 7 and ismovable axially within the sleeve or shell 7. The sleeveor shell 7 is provided with bearings 51, which support the ipe 50 centrally and so as to form a chain er between the outer wall oithe pipe 50 and the inner wall of the sleeve Means for suitably packing the bearings is provided and consists of the packing material 52 and the caps 53. The pipe -50'is provided with' centrally located ports 54, which permit communication between the pipe 50 and a sealing contact plate 60 is secured to the other end'of thepipe 50. The sealing contact plate 60 is provided eating with the interior of the sleeve 50. It

with an elastic or sealing screw 53 which cushions the tube or pipe 59 clination or curvature of the tracks.

on its return movements caused bythe'op- 'eration' of the spring 65;

The plate 60 is provided with a wide flange 68 surrounding the opening 62. The spring being located centrally with respect to'the outer edge of the flange 68 keeps the flange in contact with a corresponding plate 10 supported on the adjacent end of an adjoining car. This is particularly advantegeous when the relation of the two cars change either by reason of the change of 1e spring 65 pressing the plate 60 centrally causes the plates to remain at all times in sealing. contact and causes the coupling mechanism 'to' turn on the axes passing through the ball-and-soeket 8--9. This will keep the coupling pipes 50 on adjacent ends of adjoining cars axially in line with each other and consequently prevent any opening at the sides of the plates, which would result in the escape o! the air. or gas or vapor,

or sleeve o its normal position.-

with a passage 6 1- having an opening or port 62 and c0mmun1- materialfiii located on the outer or the intake of the air according to the pressure contained withinthe pipes.

I wish-it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims. l

Having thus described my invention what I claim 'as new, and desire to secure by Letters Patent, is,-- Y

1.
